JACQUARD MECHANISM FOR LOOMS FOR WEAVING CHENILLEWEBS.

SPECIFICATION forming part of Letters Patent No. 470,427, dated March 8, 1892. Application filed April 25, 1890. Serial No. 349,538. (No model.)

To all whom it may concern:

Be it known that I, RICHARD HARTLEY, a

citizen of the United States, residing-in the city and county of Philadelphia, State of Pennsylvania, have invented a new.and useful Improvement in Jacquard Mechanism for Looms for Weaving Chenille Webs, which improvement is fully set forth in the following specification andaccompan'ying drawings.

My invention relates to improvements in looms of the class adapted for weaving webs for the production of chenille, and has for its object the providing of mechanism whereby the movement of a single needle of the J acquard mechanism controls the delivery or feed of more than one bobbin of the filling-thread, so that the number of colors that can be employed in weaving chenille or other fabrics is not limited by the number of needles.

It consists of the construction and different combinations of parts herein set forth.

. In the drawings, Figure 1 representsa front View of the upper portion of a loom, showing a Jacquard attachment and thread-supplying devices embodying my invention, the frame being in part broken away and some of the parts omitted. Fig. 2 represents a top view, on an enlarged scale, of a sliding bar employed for shifting the carriage-raising levers. Fig. 3 represents in front view, partly broken away, the Jacquard attachment with my invention embodied therein on a larger scale than that shown in Fig. 1, showing the frame with the rising and falling carriages which carry the liftingblades for the operatinghooks and mechanism for moving said'carriages. Figs. 4- and 5 represent end views of the latch for the pivoted levers of the barshifting mechanism. Fig. 6 represents a horizontal sectional viewon line x 83, Fig. 3, on an enlarged scale. Fig. 7 represents an end view of a portion of the loom, showing the oscillatin g frame with the thread-carriers and ope r-. ating mechanism therefor. Fig.8 represents a sectional view on line y y, Fig. 7. Fig. 9 represents a plan view of a portion of the race of a loom sliowingthe shuttle and catches for opening and closing the jaws of the same. Fig. 10 represents a vertical longitudinal see- Fig. 11 represents a tion on line 2 s, Fig. 9.

view in elevation of a portion of the mechanism for oscillating the drum to which the straps or cords of the shuttle-carrier are secured. Fig. 12 represents a front View, partly broken away, of the race with operating mechanism for the shuttle.

Similar letters and numerals of reference indicate the corresponding parts in the several figures.

Referring to the drawings,A designates the frame of a loom, having secured thereon the frame B of a Jacquard attachment.

0 designates the card-pattern, and D the batten, which latter is operated by the usual mechanism, consisting of levers and rods secured to the frame and connected With and operated by the driving-shaft of the loom.

The devices for rotating the spur-wheel which operates the pattern-cards and also for operating the batten are also old and well known and are connected with the driving-shaft, and, forming no part per se of this invention, are not particularly described or shown herein, any devices that will intermittently rotate said cards being applicable-as, for instance, the mechanism shown in patent toDavis, No. 96,553, dated Novembert), 1869. On horizontal supports in said frame B are the needles E, provided with the springs F, forcing them toward the card 0. a Each of the needles E is provided with a series or number of eyes G, through which pass the vertical stems. or

shanks of a series of hooks H, so as to bel atg,

erally moved by the movements of said nee dles, and the said hooks H are arranged in rows, each hook being formed of a piece of wire or other suitable material, having the hooked upper end J and a bent lower portion K, the latter having a hook, as shown, adapted to engage with a cross-bar K of the frame 13 to prevent the falling of the hook below its proper place inthe frame. Movably located in the frame Bare the carriages L L L L having the studs Mon their ends and pro videdwith the lifting-blades N, the latter adapted to engage with the ends J ,of the hooks I-I.

For the purpose of raisin the carria es L L I. the following descl ibed mecha nisdi is employed: P P designate lifting-arms at the front and rear of the Jacquard mechanism, havingrecessed projections on their sides, so as to be adapted each to engage the un- 'der side of the studs M of either of the two adjacent carriages L L or L L and having their lower ends pivotally attached to the arms Q, which are rigidly secured to the rockshafts R, the latter being suitably journaled in the frame B or arms thereof. The said rock-shafts each have at one end the depending arm S, each of the latter being pivotally connected with one limb of one of the pivoted elbow-levers T by means of a rod U. The said elbow-levers Tare mounted on studs secured to the frame of the loom and are operated by means of the rising and falling rods V, which are pivotally connected therewith, each of said rods having a roller V at itslower end in contact with an eccentric or cam V on the driving-shaft V of the loom. The-return movement of the rods V and connected parts, after having been actuated in one direction by the cams or eccentrics on the driving-shaft, is accomplished by the fall of said rods by gravity.

To shift the arms P P so as to engage the adjacent carriages, the slotted sliding bars X on each end of the frame B are employed.

The said bars are slotted vertically and ion-- gitudinally, as at Y Y, so as to permit the movement of the vertical arms P P therein,.

andare also slotted horizontally and longitudinally, as at Y Y", so as to allow the horizontal motion of the said bars on the bolts Z Z,-Which are secured to the frame B. The arms PPhave springs P connected thereto and to the arms-Q,-wh-ich operate to insure shifting of thesaidarms P P in lowering to bring the same under the proper studs M of the pairs-of carriages.

Pivoted to a hanger A on the under side of the frame 13 are the levers B O, the said lever B being connected at one end by a cord D to 'the'hook 1 of the row of hooks farthest from the card 0 and at its other end being connectedbya-spring-andcord connection E to an arm F, rigidly attached to a rockshaft G, which is journaled in the frame 13 andihas an arm H at each end thereof engagi-ng inrecessed-portions of the sliding bars X, so as to move the same when the shaft G is rocked. The lever O is connected at one end to the hook 2 of the next-to the last row of :hooks from the card 0 by-means of a cord J andat the other end has a spring-and-cord connection E with an arm K rigidly secured to the rock-shaft G ,the-said cord E passing over a roller M above the arm K of the rocki n g-shaf t. a rod M secured to either of the levers H or N, one only being shown, each being of the form of a segment and having in one of its sides a curved groove Q. Each of the elbowlevers R, which are pivoted to the frames N, has a limb passing through a slot S in said frame and engaging a pin T, which latter is adapted to be projected into the grooveQ or be withdrawn from the same, according as the said elbow-lever R is operated by means of a cord B which is attached thereto and to one of the hooks H.

In the lower part of the frames N are openings U, through which are passed the threads of the filling. On the pivotal support or connection of each of the frames N are mounted the arms or levers V W, which are operated, respectively, by the pivoted arms X Y, attached to the arms of a lever Z, the latter being rigidly secured'to a.rock-sh aft A which is oscillated by means of the arm B rigidly secured thereto at one end. A rod 0 pivotally connects the arm B with a Weighted pivoted lever D which is raised by an eccentric E on the driving-shaft W of the loom.

To keepthe frames N in fixed position during delivery or feed of the thread, the under side of each of the same has notchesor recesses, as at F to receive a wedge-shaped projection G on a pivoted lever H which latter is raised or lowered by means of a lever J operated by an eccentric K on the driving-shaft NV at each rotation of the said driv- A spring connection consisting of J and adapted to work in a slot in the other arm, and an expansion-spring N3, surrounding the rod M is provided to insure a yielding contact of the projection G2 with theunder side of the frame N, so as to prevent a binding of said parts.

In the ends of the arms V W are studs P adapted to enter the groove Q and come in contact with a pin T, projected therein, so as to aid said arms V and W in moving the frame N the proper distance to bring the required color in reach of the shuttle Q The shuttle Q is provided with spring-jaws S at each end thereof, the said jaws consisting of pivoted levers having the projecting arms S at the inner ends thereof, the said jaws being adapted to clasp and to retain while closed the end of the filling-thread within the same. Said jaws, as shown, are constructed of two parts or levers pivoted together and tothe shuttle-body and bent outward at the rear to provide for opening the biting ends and inclose springs S for normally holding said jaws closed. I do not limit myself to the precise construction shown, as many forms of jaws might be employed.

For opening the jaws so that one pair of them may release the thread which has been passed through the'shed and the other grasp the thread to'be passed through, two pairs of spring-actuated catches T are'located at each end of the loom, the said catches bearing against the jaws, so that when the shuttle has left the shed the thread which has become filling is dropped from one of the pairs of jaws and the other pair of jaws is ready to receive the new color or filling-thread. The jaws yield as the shuttle enters the shed, so that the pair of jaws which has come in contact with the new thread will retain the same and carry it through the shed. The shuttle moving in the direction of the arrow, Fig. 9, the pairs of jawsS to the left will travel over with its thread until the first pair of catches T on the right-hand side of the loom is reached by such pair, the said catches opening the said jaws, and thereby setting free the thread carried thereby. The parts are so timed that the above first-named jaws release the thread carried thereby just before the second set of jaws to the right grasps a thread. The opening and closing of said jaws is attained by the catches T which are so arranged that when the jaws to the left on the shuttle are on the outside of the outermost catches T to the left of the loom as the shuttle moves to the right the said jaws will press the catches at the left-hand end of the loom backward against the tension of the adjacent springs S and said jaws will pass over and not be affected by said left-hand catches and will continue closed until the first pair of direction, studs S aresupplied, against which the catches are always caused to normally bear by springs S The shuttle-carrier B is operated by means of a cord or chain U the said cord being passedaround the pulleys V at the sides of the loom and having its endssecured to an oscillating drum V which is mounted on the shaft X the latter carrying a pinion Y operated by a segmental rack Z which meshes therewith, the said rack being oscillated by a rod Z and a crank-arm A attached to the drivingshaft W of the loom.

The pattern-card C has a row of openings on oneof itsedges to receive the spurs of a wheel (3 on its frame or batten, which moves the said pattern-card C an opening at every other pick, said operation of wheel O being accomplished by any suitable ratchet-andpawl or analogous mechanism. (Not shown, as it forms no part of my present invention.) Adjacent to the said outer rowof openings are two inner rows, which are adapted to control the movement of the first'and second ncedles, and thereby the hooks 1 and 2, to which the levers B and G are connected; Other openings are formed in the card corresponding to the remaining needles to be actuated.

The operation is as follows: The drivingshaft V bein g set in motion, the batten of the pattern-card Ois oscillated therefrom, so that the card is brought in contact with the needles E, all of these, exceptthose entering openings in the said card, being forced backward and with them their hooks, so that the latter are out of i the way of the lifting-blades N of the carriages. The carriages L,L', L and L are arranged in pairs, the left-hand pair L L being designed to operate the colors on the left hand of the loom and the right-hand pair L. L to operate the colors on the right hand of the loom, and the left-hand carriage of each pair (or the carriages L L are designed to be alternately operated by the arms P P, while the bars X are in one position, and the right-hand carriages of each pair, or the carriages L and L to be alternately operated by the said arms when the bars X have shifted their position. In the position of the parts shown in Fig. 3 the arms P are about to begin their descent, having raised the carriage L and by means of its blade N, the hook 1, the needle of which has entered an opening in the card 0, so that the lever B has been operated so as to draw downward upon theconnection E and the arm F of the rock-shaft G, thus oscillating the latter with its arm H, and thereby shifting the barX to the position shown. when the arms P have completed their descent, the arms P rise and lift the carriage L sothat a hook on the corresponding row is raised and draws upon a cord B ,.thus moving an elbow-lever B so as to project its pin T in the groove Q, and thuscontrol or regulate the throw or movement of the righthand segmental frame N, which movement is accomplished by the action of the arms V W, operated by the arms X, Y, andZ and rockshaft A the latter being operated by the arm B rod- 0 arm D and eccentric E onthe driving-shaft W. The frame N is now in position for the shuttle to take hold of the proper color previous to its flight through the shed. When the arms P have completed their descent, the arms P then rise and, owing to the position of the slot-ted bars X, raise the carriage L, so that a hook on the row of its blade is raised according to the pattern-card, thus actuating a pin in the left-hand frame N and regulating the movement of the latter and therebythe position of the fillings. This movement alternately of the carriages L and L is continued according to the pattern, the needle of the hook 2, the movement of which actuates the. lever 0', meeting a blank in the card, so that the said needle is forced back and its hook is out of the Way of the lifting-blade. When it is now desired to change the colors, the needle connected with the hook 2, operating said lever O, enters an opening in the card, so that the hook 2 is :in the way of a blade and is lifted by the rais ing of the carriage L by the arms P, so that the lever O is moved, drawing upon the connection E and thereby raising the arm K, thus rocking the shaft G and arms H, Whereby the bars X are shiftedto the left. When the arms P complete their descent, the arms P rise and, engaging the carriageLZ lift the same and the hook of that row left in its way by its needle entering an opening in the pattern-card. When the arms P have completed their descent, the arms 1, rising, engagethe carriage L, being guided in the slots Y of the bars X, so that the recessed projectionsinttheir left sides are under the studs M of thesaid carriage. The alternatelifting and falling of the carriages-L and L will continueas longas the needle of the hook 1 conraised andthe lever B operated and rock the shaft G and the arm H, and thereby shift the bars X, the Walls of theslots of which serve as guides to direct the bearings or re-' cessed projections on thesides-of the arms P P under the studs of the carriages. To

keep either one of the levers B C in fixed position until the other is operated by the raising of its hook, a latch O is employed.

The said latch is pivoted toa slotted hanger D secured to the frame of the attachment,- and is provided with a pin E which projects from both sides thereof and across the slots F in which the ends of the levers B and 0' work. ward motion comes in contact with the pin, it oscillates the latch, so that the head thereof is swung over the .top of the lever, thus keeping it in place until the other lever descends and strikes the pin on the other side of thelatch. WVhen the latter is tilted or swung over so as to release the first lever, the end of which is moved upward andout of engagement of the said latch, the second lever is secured in. place by the head of thelatch.

The matter relating to the oscillating frame 1 with the thread-carriers thereon, described in this specification and shown in the drawings, but not specifically-claimed herein, is reserved, being described, shown, and claimed by me in a pending application for Letters Patent for an improvement in looms filed May 23,
